BOSTON (AP) — Boston is bracing for a World Series parade that is expected to draw hundreds of thousands of fans into the city to thank the Red Sox for a remarkable season.

The duck boat parade is set to being at 10 a.m. Saturday, when the team's players will climb aboard 24 amphibious vehicles at Fenway Park, then travel through the city and finally go on to the Charles River.

Security will be tight during the event, with extra police on hand throughout the day and random searches of backpacks along the parade route.

The Massachusetts Bay Transportation Authority is planning to run extra trains and subways at a rush-hour level.

The Red Sox defeated the St. Louis Cardinals 6-1 at Fenway Park on Wednesday to take the series in six games.
